How do I solve this?

A cinema has two different prices for tickets: one price for children and one price for adults.

: 35 cents children's tickets plus 20 adults cost a total of 287.5

:25 cents children's tickets plus 30 adults tickets cost 307.50

How much does a single adult ticket cost, in dollars
